I'm just starting to think about what actual chemicals are going into my liquids..I don't any with the d word...lol
This is Another benefit to DIY. You have Control of Exactly what goes into your e-liquids.
BTW - Yes... Diacetyl should be (IMO) a Concern. But what people should Also consider is Acetyl Propionyl.
Because when the Initial concerns over Diacetyl surfaced, many Retailer switch to Acetyl Propionyl so they could say that there e-liquids were Diacetyl Free.
Unfortunately, Acetyl Propionyl is probably just a Potentially Harmful as Diacetyl. So removing Diacetyl from e-liquids is Good. Not say'n that it Isn't. But if it is Replaced with Acetyl Propionyl, then we might not be getting any closer to a "Better" e-Liquid.
